Embodiment Construction

[0021] A hollow split-type conductive plastic potentiometer, which is installed separately and uses a hollow hollow shaft to design cables, air passages, and transfer shaft channels. The number of spring coils, pitch, radial elastic deformation, and radial elastic pressure The torque design enables the planar spring to meet the working requirements of the potentiometer. At the same time, an arc-shaped resistor body made of conductive plastic is arranged in the conductive matrix, which reduces the required installation accuracy and ensures large radial and axial clearance tolerances. Split installation can be realized, such as figure 1 As shown, including base-1, bearing-2, hollow shaft-3, conductive base-5, insulating bushing-6, conductive ring-7, planar spring-8, current collector-9, contact reed-10, Brush-11, lead-out cable-12, block-13, pressing block-14, wherein:

[0022] The base is fixed on the external mechanism through the threaded hole set at the lower end, as the ca...

Abstract

The invention discloses a hollow split type conductive plastic potentiometer which comprises a base, a bearing, a hollow shaft, a conductive substrate, an insulating bushing, a conductive ring, a plane spring, a current collector, a contact reed, an electric brush, a leading-out cable, a stop block and a pressing block. Through the hollow design of the hollow shaft and the attribute presetting ofthe plane spring, the split installation is realized while the use requirements are met, the problems that the traditional integrated potentiometer is easy to generate shafting deviation, and the precision and the service life are not as expected due to large volume and high requirement on shafting precision are solved, and the structure is stable.

Description

technical field [0001] The invention relates to a hollow split conductive plastic potentiometer, which belongs to the field of aerospace sensor design. Background technique [0002] The potentiometer is a resistive element with three terminals and the resistance value can be adjusted according to a certain change rule. A potentiometer usually consists of a resistor body and a movable brush. When the brush moves along the resistor body, a resistance value or voltage that has a certain relationship with the displacement is obtained at the output end. [0003] At present, with the continuous development of aerospace technology, the development of strategic and tactical weapons tends to be miniaturized and high-precision. The reliability and service life of the potentiometer put forward higher requirements. [0004] The traditional potentiometer is an integrated potentiometer, that is, the rotor and stator of the potentiometer are integrated into a whole potentiometer. The v...
